eaes DAVID MUNSON, OF INDIANAPOLIS, INDIANA. Letters Patent No. 84.210, dated November 17, 186 8.

IIWPROVEMENT IN LIGHTNING-RODS.

The Schedule referred to in these Letters Patent and making pan: of the lame,

To all whom it may CO'MCGITL:

Be it known that I, Davin MUNSON, of lndianaps olis, in the county of Marion, and State of Indiana, have invented new and useful Improvements in Lightning-Rods; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawing, and to the letters of reference marked thereon, making part of this specification.

Myinvention relates to form of the rod, and to the mode of fastening together the sections of which it is composed, combining many receiving-points with large conducting-surface and an economical and substantial construction.

Figure 1 is a side view,

Figure 2, an edge view, and

Figure 3, an end section view of the rod.

Similar letters of reference indicate the same parts in the several figures.

The following description will enable skilled artisans to make and use my invention.

I make my lightning-rod .of sheet-copper, out into strips of suitable length and width for working, which are formed as shown in the drawing.

The sections A are lapped on to each other at the ends, and are firmly secured together by cutting into the edges so as to form. lugs or cars B, which are turned down, as shown, leaving notches, and thus also forming points 0 along the edge of the rod to receive the electricity. The form of the rod makes a continuous gutter or trough, which it is designed to put up in such manner that all that portion of it that lies on the roof, or in a horiZontal position, will have the open side up, so that it may receive and conduet the rain and dews that fall upon it to the ground, for the purpose .of keeping it moist around the rod.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is

The lightning-conductor, composed of the sections A, formed and secured together as and for the purpose set forth.

DAVID MUNSON.
